USB4 and Thunderbolt 4 in Video Production
In video production, equipment connection standards are important factors directly affecting efficiency and quality. The recently introduced USB4 and Thunderbolt 4 are attracting attention as advanced standards enabling fast data transfers and flexible connections between diverse devices. Both offer transfer speeds of up to 40 Gbps, but their specific differences and how best to use them may not be immediately clear. This article explains their features and differences in an accessible way, along with practical applications in video production.
How Do USB4 and Thunderbolt 4 Differ?
Let us first look at the basic differences. USB4 significantly advances earlier USB standards, principally supporting data transfer, display output, and power delivery together. Meanwhile, Thunderbolt 4 is based on USB4 but meets stricter performance requirements. For example, Thunderbolt 4 always provides a 40 Gbps connection, while USB4 may be limited to 20 Gbps depending on the device. Thunderbolt 4 also guarantees output to multiple 4K displays or one 8K display and is intended for professional environments. Thus, while USB4 is a general-purpose standard aimed at widespread adoption, Thunderbolt 4 can be considered a premium option.
Practical Applications in Video Production
How can these standards be used in production? For example, when storing and editing large 4K or 8K video files on an external SSD, a Thunderbolt 4-compatible SSD can provide fast, stable data transfer. This significantly reduces waiting during editing and lets you concentrate on creative work. USB4 also allows you to integrate various devices at relatively low cost. A USB4-compatible hub, for example, can connect cameras, external storage, and displays together, keeping your workspace tidy. For video production, the ideal approach is to use Thunderbolt 4, combining stability and flexibility, as the main connection and supplement it with USB4 as needed.
Choose the Standard That Suits Your Production Setup
USB4 and Thunderbolt 4 each have distinctive strengths, and the best choice depends on the application. Thunderbolt 4 is ideal when high stability and performance are required professionally, while USB4 can be sufficient when affordability and convenience are priorities. Because the standards are compatible, you do not need to replace every device at once. Start by reviewing your workflow and considering which parts need high performance. Then choose the standard that suits you to build an efficient, comfortable production environment.
